RIB-CAGE: More ventilation. Same stability. No contradiction.

RIB-CAGE: More ventilation. Same stability. No contradiction.

If you want a helmet with lots of large ventilation openings, you normally have to compromise on stability. If you want maximum stability, you get less airflow. The RIB-CAGE system resolves this conflict with a clever piece of engineering: rib-shaped reinforcement elements inside the EPS inner shell that take on load-bearing tasks where material is missing due to ventilation openings.

The result is a helmet that can do both: generous ventilation and structural integrity. Not a compromise, but an engineered solution.

The problem RIB-CAGE solves

The problem RIB-CAGE solves

Bike helmets involve a fundamental trade-off:

  • Large ventilation openings = better cooling, but less material = weaker structure
  • Stronger structure = more material = smaller openings = poorer cooling

For helmets used on long tours, at high speeds or on the trail, this is a real challenge. Riders want both – and RIB-CAGE makes both possible.

How RIB-CAGE works

The solution comes from engineering: rib-shaped reinforcement elements in the EPS geometry that work on the principle of a truss. Forces are not concentrated locally but distributed over a larger area. Critical zones are stabilized. Material can be reduced where the ribs take over the load-bearing function.

In concrete terms, this means:

  • Larger ventilation openings are possible without loss of stability
  • Impact forces are better distributed
  • Torsional stiffness increases
  • Weight remains optimized

What this means for the rider

These three things come together in the Reach through RIB-CAGE – for riders who are out on asphalt, gravel and in everyday life and don't want to give anything up.

  • A cooler head on long climbs.

  • More stability on impact.

  • A lighter helmet feel.
RIB-CAGE and Mips® – two levels, one strategy

RIB-CAGE and Mips® – two levels, one strategy

RIB-CAGE strengthens the structure of the helmet. Mips® adds rotational protection for angled impacts to the safety concept. Both technologies address different aspects of safety and are used together in the Reach DT-1 and Reach AR-1. The result is a helmet with a well-thought-out construction on multiple levels.

What is the RIB-CAGE system?

Rib-shaped reinforcement elements in the EPS inner shell that take on load-bearing tasks where ventilation openings remove material – for more ventilation without any loss of stability.

Why does a helmet need RIB-CAGE?

Because large ventilation openings weaken the EPS structure. RIB-CAGE compensates for this effect with targeted reinforcement ribs.

Which KED helmets feature RIB-CAGE?

Reach DT-1, Reach DT-1 Bestzeit and Reach AR-1.

Is RIB-CAGE the same as Mips®?

No. RIB-CAGE is a structural design solution. Mips® is a protection system against rotational forces. Both can appear in the same helmet and complement each other.

Does RIB-CAGE make the helmet heavier?

No. The ribs allow material to be reduced in other areas, which contributes to an optimized weight.
